Gate valve location question.

[Wsnider]

I'm doing a DT upstairs with a sump in the basement. Is there any reason I can't or shouldn't put the gate valve in the basement? For me, it would be much easier to access, since I don't want to crawl under the tank to reach it. Otherwise I'll have to make a pipe with a notched end to use as a key.

No reason. It will be quieter in the basement as well. The only slight issue with it being in the basement is that for tuning the flow you may have to go back and forth between the basement and the DT. You don’t need to tweak that often however. After a while, you get to learn how much water is coming out of the e drain and don’t need to go back and forth.

I didn't even think about noise so thats a nice bonus. Thx for the fast reply. Yeah I figured there'd be alot of stairs for that initial start up...lol.

Another tip is that the gate valves are extremely sensitive. So when adjusting do very small turns one way or the other. I’m talking like an 1/8th of a turn can be the difference.

+1 for the basement location. I'm assuming this is going to be a full siphon drain you're talking about. You want the valve as close to the pipe exit as feasible so that the pipe above the valve is full of water.

If the valve is too high above the exit point you can get a partially filled pipe after the valve and that section of pipe would make noise as it drains to the sump.

As mentioned above, tuning for the right flow might be a bit of a pain at first, but I think its worth the reduced long term noise.

Thx all. Looks like it being in the basement is the winner!

+1 on basement. You always want it close to where the water dumps out so the whole line fills with water. If it doesn't, you will have a noisy line dumping out.

Plus a tip for basement sump owners:
No need to run up and down stairs.
Just watch the emergency line. When it's a slight trickle, there will be slight bubbles being made on the emergency line. If to much water flowing, lots of bubbles. If no bubbles, no water at all.
So I will close the line, wait for bubbles. Slowly open it until the bubbles are slow. If the bubbles stop I know I went to far. Just open it slightly.
If your worried about a flood, this is what the emergency is for. If you're worried, you have bigger plumbing problems.

Bean...its an IM 100 INT. Good points on the tuning...thx!

In addition to the gate valve in the basement, maybe add a ball valve at the tank for some redundancy/safety shut off

I found it harder to balance “quiet” when gates far below overflows.
Mine run right underneath the overflow and seem easier to control the flow, 15ft to the basement.
